thunderbird vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04
- Ubuntu 18.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client

Details:

A type confusion bug was discovered in Thunderbird. If a user were
tricked in to opening a specially crafted website in a browsing context,
an attacker could exploit this by causing a denial of service, or
executing arbirary code. (CVE-2019-11707)

It was discovered that a sandboxed child process could open arbitrary web
content in the parent process via the Prompt:Open IPC message. When
combined with another vulnerability, an attacker could potentially exploit
this to execute arbitrary code. (CVE-2019-11708)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 19.04:
thunderbird 1:60.7.2+build2-0ubuntu0.19.04.1
